UNITED STATES THOMAS BEEOHER,

To all whom it may concern.-

) Be it known that-LTHoMAs BEEOHER, of

New Haven, in the county of New Haven and State of Connecticut, have invented a new Im- 5. provement in' Snap-Hooks; and I do hereby declare the following, when taken in" connection with accompanying drawingandthe letters of reference marked thereon, to be a full,

clear, and exact description of the same, and

which said drawing constitutes part of this specification, and represents a sectional side view. l l

This invention relates to an improvement in that class of snap-hooks in which the mouth is closed by a longitudinally-sliding bolt. In

the usual construction of this class of hooks barrel and the bolt arranged within the barrel, with a spring behind it to force it forward to ward the end of the hook. Through the bary rel is a slot through which a thumb-piece'on the bolt plays. l In the manufacture of thisclass of hooks there is considerable difficnlty in obtaining 2 5 perfect castings, in that thebarrel is requiredto be cored; but, at best, so imperfect is this coringthat itis found necessary generally to bore out the barrel, and if the coring be so perfect 1 as not to require boring the necessary treato ment of the casting to acids leaves more or less of the acid in the barrel or spring-chamber, which quickly acts upon the spring introduced therein, so that thedestructionof the spring is a very frequent occurrence due to this presa 3 5 once of acid. Agaiinthe barrel forms a receptacle for dirt or foreign substances which may enter or work in through the slot, or through the opening which is necessarily lefttherein for water to escape.

The object of my invention is to overcome these difliculties; and it consists in the con- "structionof the hook, as hereinafter described, and more particularly recited in the claim.

A is the body of the hook, at one end con- 5 structed with a loop, 13, or otherdevice, as a convenient means for attachment, and at the other turned upward and over to form the hook C. l y D is an arin, starting from the loop end and extending forward in line with the ends of the hook and in a plane parallel with the back.

so as to slide freely on the arm toward and from the end a of the hook, the arm D serving as a guide for the movement of the sleeve, directing it in such movement so that it stands in line with the nose of the hook, as shown. This sleeve is made hollow or tubular, and within the sleeveis a spring, F, resting one end against a shoulder, d, on the arm and the other against a shoulder, e, in the sleeve, the tendency of the spring being to force the sleeve toward the nose of the hook, yet yielding for the movement of the sleeve away from the nose to open the mouth of the hook, as seen in broken lines.

Preferably the nose of the hook is made with a slightly-projecting stud to enter that endof the sleeve, so as to form a support for that end of the sleeve when the hook is closed. j The sleeve may be provided with a thumb-piece or projection, f, which will serve as a convenience hook at the opposite end, all apertures to the q i spring-chamber are closed when the hook is in use.

Preferably I form a lug, h, on the inside of y the body of the hook extending toward the sleeve, to prevent the ring or whatever the hook may be attached to passing back beneath. and so as to interfere with the working of the; sleeve.

I claim The herein-described snap-hook, consisting of the body A, terminating in a hook at one end and a device forattaching the hook at the. opposite end, an arm, D, extending forward in line with the nose of the hook, combined with the tubular sleeve E, arranged on the bar D,

and a spring within said sleeve, the action-of which is to force thesleevetoward the nose of the hook, substantially asldescribed.
